50 km/H towards west, the car was going in north direction then while turning 90 degree right it tells that it was then moving in the direction west, it is clear that the speed was not varied

The correct answer given is B. 70 km/h towards south west but how? I need explaination, so i posted the question

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
